4.2 Most important symptoms/effects, acute and delayedMay be fatal if inhaled, swallowed or absorbed through skin. Vapor or mist irritating to the eyes, mucous membranes and upper respiratory tract; causes skin irritation. Absorption into body leads to the formation of methemoglobin which, in sufficient concentration, may cause cyanosis. Onset may be delayed 2-4 hours or longer. Exposure can cause nausea, dizziness, headache, damage to the eyes, and blood effects. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryImmediate First Aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aromatic hydrocarbons and related compounds/

- Toxicity to microorganisms: no data available
AEROBIC: A Warburg respirometer study utilizing an activated sludge seed and 6 hr of incubation resulted in a 2,6-xylidine depletion of 33-37% at a concentration of 20 ppm(1). In a 6 week soil degradation study using (14)C-labelled 2,6-xylidine, 8.4% of applied radioactivity was recovered via CO2 evolution in non-autoclaved soil while 0% CO2 evolution occurred in autoclaved soil(2). In a soil degradation study conducted in glass vessels using Chernozem soil, 2,6-xylidine (at 500 mg/L) was degraded after 3 days of incubation with >90% recovered in transformation products(3). Using OECD Guideline 301F (Ready Biodegradability: Manometric Respirometry Test), 2,6-xylidine (at 100 mg/L) reached 4, 8, 25, 38 and 69% of its theoretical BOD after 7, 13, 36, 42 and 70 days. respectively(4); these results indicated that 2,6-xylidine was not readily biodegradable according to OECD criteria, however, it is biodegradable after extended adaptation(4). In another OECD Guideline 301F study, 2,6-xylidine (at 100 mg/L) showed no bidegradation after 33 day(4). Using OECD Guideline 302B (Inherent biodegradability: Zahn-Wellens/EMPA Test) and an industrial activated sludge seed, 83% of initial 2,6-xylidine was removed from the aqueous test system after 11 days, however, the substance was mainly removed via volatilization(4). 2,6-Xylidine, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5).
12.3 Bioaccumulative potentialAn estimated BCF value of 8 was calculated for 2,6-xylidine in fish(SRC), using a log Kow of 1.84(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilUsing a structure estimation method based on molecular connectivity indices(1), the Koc of 2,6-xylidine can be estimated to be 190(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,6-xylidine is expected to have moderate mobility in soil. Aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(3,4), suggesting that mobility may be lower in some soils(SRC). In a short term soil adsorption study using 14C-labelled 2,6-xylidine, 66% of the applied radioactivity was bound to the soil (3.4% organic matter, 36.6% sand, 28.2% silt, 35.2% clay) after 24 hrs(3).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning.
